To all whom it may concern:

Be it known that I, Fran]; M. Pmncn, citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Double- Wrapper Wrapping-Machines; and I- do hereby declare that the following is a full, clear, and exact description of the sa1ne,'ref erence being had to the accompanying drawings,- and to the numerals of reference marked thereon, which form a .p'art of this specification. p

This invention relates to an improved type of wrapping machine adapted to apply a plurality of wrappers on annular sha ed bodies. In most of the types of wrapping machines heretofore designed, has been applied upon the article by a revolving shuttle generally having a removable section to permit insertion of the article to be wrapped through the eye of the shuttle, after which the section is replaced for the wrapping operation. However, in this invention the shuttle is provided with a normally open ga to permit insertion into or removal of artxc es from the shuttle with out necessitating adjustment of the parts of the shuttle, and the shuttle is so mounted and driven as to apply one or more wrappers on the article by merely imparting'a simple revolving movement thereto.

It is an object therefore of this invention to construct a wrapping machine capable of applying one or more wrappers upon an article and permitting insertmn and removal of the article into and from the machine adjustmentv of the wrapwithout requiring per applying means.

It is also an object of this invention to construct a-wrapping machine adapted to support, advance, and revolve an annular article through the eye of an o n pap shuttle which is also revolved by suitab e mocha nisms and carries a plurality of reels of wrapping material for application upo'n thearticle, rotating therearound as the article is revolved therethrough.

the wrapper It is also an object of this invention to construct a wrapping machine adapted to support annular articles in upright posi-' t1 on during a'wrapping operation, and provlded with an improved adjusting means to permit adjustment else to centralize the same in the wrapping shuttle.

It is also an object of this invention to construct a wrapping machine provided with an open up shuttle with a series rollers mounted on an open guide to receive the shuttle thereover to support the same rotatably thereon, permitting the shuttle to be rotated for application of a" wrapper upon an article without necessitating closure of the gap in the shuttle for the purpose. v

It is furthermore an important object of this invention to construct a wrapping machine capable of applying one or more wrappers upon an annular articleby means of an open gap shuttle adapted togbe revolved aroundthe article as the 'niticle is moved therethrough, and with n1ans conveniently accessib e at the top f'the machine for self-adjustin the support for the article, for articles of lfi'erent size to secure proper alinement thereof through the eye of the shuttle. a

It is finally an object of this invention to construct an improved type of double wrapper wrapping machinecanable of operating aat high speed upon articles of different size, v permitting insertion and removal of the ar- 7 ticle into and from the machine without necessitating-"adjustment of the wrapper carryingvshuttle and provided with clutch controlled driv'- mechanism associated with a brake who when the drive is disconnet/ted from the machine the brake is applied to stop movement of the arts.

The invention (in a preferred orm) is illustrated in the drawings and hereinafter more fully described. p

As shown in the drawings:

The frame of the machine embraces two similarly constructed side frame members 1 and 2, respectively, which are integrally or otherwise rigidly connected one to another at their upper ends by an arched cross frame member 3, and a lower cross frame member 4, which is rigidly bolted to said side frame members 1 and 2. A stay rod or bar 5, is also rigidly secured between said side frame members 1 and 2, at the lower end thereof, at the front of the machine. Bolted on the rear surface of the side frame member 1, is an n wardly curved extension bracket 6, affordmg a hearing at its upper end for a drive shaft 7 which also extends through bearin 8 and 9, provided on the inner surface of said side frame member, as clearly shown in detail in Fig. 3. A large driving pulley 10, is mounted upon said shaft and associated therewith is a clutch member 11, whereby said pulley may be connected with the shaft to drive the same.

For the purpose of actuating said clutch, a Ion lever 12, is pivoted in a bracket 13, secure on the rear surface of said side frame member 1, which is connected to a short lever 14, which is in turn connected to said clutch 11, to engage or disengage the same with said wheel 10, as the case may be. The outer end of said lever 12, extends beneath a vertically mounted retaining bar 15, secured on the outer surface of said side frame memease-2e her 1, to limit the movement-of said lever 12. Mounted on the inner surface of each of the side frame members 1 and 2, are upper and lower brackets, denoted respectively by the reference numerals l6 and 17, in which are secured upright guide rods 18. A traveling carriage 19, is provided. consisting of side frame members having extensions 20 and 21, respectively, which fit slid-ably upon said upright rods 18. and journaled in said carriage are a pair of shafts on which supportin and driving, rollers 22 and 23. are mounted. the surfaces thereof, as clearly shown in Figs. 1 and 5, corrugated to insure positive contact with an annular article such as a tire 21-, supported thereon for wrapping, as shown in Fig. 1.

For the purpose of insuring simultaneous rotation of said rollers 22 and 23,in the same direction, sprocket wheels are secured on the outer ends of said shafts on which said rollers are mounted, and a chain 24, is trained thereover. For the purpose of imparting a drive to said rollers 22 and 23, a shaft 25, is mounted vertically in bearings for the purpose on the inner surface of the side frame member 1, and at its upper end is provided with a worm wheel 26, meshing with a worm 27. secured on the drive shaft 7. At one side of the traveling carriage an extension 28, is formed, through which said vertical shaft 25. extends, and above which a bevel pinion 29, is feathered on said shaft, which meshes with a bevel pinion 30, secured upon the. same shaft with the roller 23. One side of each of said upright guide rods 18, is provided with a series of teeth. as clearly shown in Fig. 6, and mounted in the carria e 19, is a. horizontal shaft. 31, the ends of w ich extend through the lower members 21, and are each cut to form small pinions 32. to mesh with the teeth out on said guide rods. so that when the shaft 31. is rotated the carriage 1!), is raised or lowered thereby. For the purpose of rotating said shaft 31. one end thereof is extended, as clearly shown in Fig. .6, and is provided with a sprocket wheel 33, about which a. chain 34, is trained. with one end of said chain, as clearly shown in Figs. 2. 3, and 10, secured on the hub of a disk 3."). journaled on a stud on the frame member 1, and the other end of said chain 34. trained about a pinion 36, and secured on the hub of another disk 37, journaled on on said frame member 1. Each of said disks 35 and 37, have one end of spiral springs 38 and 39, respectively, connected thereto, the other ends of the springs being connected upon the stud on which the disk is journalcd, in such a manner as to rotate said disks in opposite directions. Consequently with movement of said chain 34, as the pininn'33, moves toward or away from the pinanother stud i of brackets 44, which 1,263,924 3 ion 36, with adjusting movements of the can bearing on said end of said lever and also riage 19, the slack in said spring 34, is taken beneat an adjustable wing nut 62, so that 36, is secured upon the end a short shaft journaled in a bearing provided in one of the upper brackets 16 and the other end of said shaft, as clearly shown in Fig. 4-, is cut to form a small worm pinion 4:0, meshing with a worm 41, on the lower end of an inclined shaft 42, which is mounted in hearings on said frame member 1, and at its upper end is provided with an actuatin handle 43.

ounted on said carriage 19, are a pair are slidable toward andaway from one another, each having journalcd at its upper outer end inclined guide rollers 45, which bear against the sides of the tire or other article being wrapped. For the pur ose of adjusting said brackets and said ro lers therewith, a double lead screw 46, is

up. Said pinion 0 ournaled in said carriage 19, and each of said brackets 44, is provided with extensions 47, which are internally threadedafnd through which said lead screw extends and engages therewith. Said lead screw at one of its en's is extended and provided with a sprocket Wheel about which a chain 48, is trained, and said chain is also trained about a sprocket wheel secured to a hand wheel 49, which is manually actuatable to thereby rotate said lead screw 46, and adjust said guide rollers45, toward or away from one another, as the case may be.

Formed on or secured beneath the arched cross frame member 3, is 2. depending crescent sha. ed frame 50, shown in dotted lines in, Fig. lion the forward surface of which isisecured i close relation a number of rollers 51. otatably mounted upon said rollers 51, i an open gap circular shuttle 52, which, clear! y shown in the sectional view in Fig. 3, is provided with a groove on its inner periphery which fits over said rollers 51. to n. fintain the shuttle associated therewith. .\E "An-s is provided for driving said shuttle 52, and for this purpose a drivin ulley 53, is secured upon said drive sha t ,7 at one side of said shuttle, and an idler pulley 54, of similar size and construction is mounted on a short shaft in bearin s 55, secured on the inner surface of the rame member 2, and as clearly shown in Fig. 1' smaller idler pulleys 56 and 57, are mounted on the upper end of the machine, permitting a driving belt 58, to be trained a out all of said pulleys and around the upper outer eriphery of the shuttle. In order to maintain t e requisite tension upon said belt 58, said idler pulley 57, is adjustably mounted on the end of a lever 59, pivoted at its middle on the cross frame member 3, and at its other end loosely engaging on an upright rod 60, with a spiral compression spring 61,

site ed .terial, denoted by the said pulley 57, is 'normall thrust u wardly beneath the belt trained tlierearouml.

Journaled on the front surface of said shuttle 52, are spindle or wra per carrying reels 63 and 64 respectively, tl ie one for paper and the ot or preferably for burlap, as in wrapping coils o wire although of course the same or different material for wrapping may be used upon said reels. Adjacent the reel 63, is a tension and folding device mounted on a plate 65, .having a pin lity of pins 66, arran ed in staggered r ation thereon around w ich the wrapping material, denoted by the reference numeral 67, is trained, and thence through a pivoted tapered double folding or creasing device 68, which folds both edges of the material being led to the article being wrapped. The folder device 68, as clearly shown in Figs. 1 and 12 to 15, consists of one tapered plate having another plate 68", riveted thereto and spaced therefrom and bent over the edges of said tapered plate so as to fold the oppoes of a strip of material drawn there through, and a sto pin 67, is provided to limit the outwar swing of said device. Similarly mounted adjacent the reel 64, is another tension device comprising a plate 69, having a pluralit of pins 70, projecting therefrom around w ich the wrapping mareference numeral 71, is trained, and thence around a tapered guide roller 72, to the article being wrapped.

For the purpose of maintaining the artiolebeing wrapped properl through the eye of the shutt e 52, guiding means is provided comprising three rollers 73, arranged in the angled relation shown in Fig. 1, all ivoted on one end of a lever 74, which, at ts other end, is pivoted upon 106 a rearwardl extending bracket 75, secured to the arched cross frame member 3. Formed integrally onsaid lever 74, on each side thereof, are upwardly extending plates 76,

which extend on each side of the bracket 75, 110

thereby guiding said lever 74, in its pivotal movement, and a pin 77 is secured between said upright plates 76, to limit the down ward movement of saidlever 74.

. As clearlfy shown in Figs? and 3, the up- 115 per edge 0 the rear nd of said lever 74, is provided .with a series of notches and a weight 78, provided with a pin 79, secured in extensionsthereof, is adapted to be suspended on said lever with. said pin seating 120 in said notches to permit adjustment of said weight at different points on said lever, said weight havin a forward extension 80, which bears upwar ly beneath the under surface ofsaid lever to brace the weight in its at- 125 ta'ched position on the lever.

centralized In order to bring the machine to rest immediately after disen agement of the clutch 11, by the lever 12, a Erake is provided comprising a brake drum 81 formed on the rear surface of the pulley a3, and disposed to bear against the under side thereof is a brake shoe 82, shown in detail in Fig. 9, mounted on the end of a pivoted lever 88,

which is mounted on said side frame member pose the 1. The other end of said lever 83, bears upon a compression spring 84, which normally acts to maintain the brake shoe 82, away from the brake drum 81, but the position of said lever 83, is such that when the clutch releasing lever 12, is thrown down to release the clutch 11, said lever 12, contacts the end of said lever 83, depressing the same against the compression of its sprin 84, and ap lying the brake shoe on the bra to drum.

he operation is as follows:

The article to be wrapped, shown in Fig. 1, and denoted by the character X, is placed into the machine resting upon the rollers 22 and 23, and projecting through the eye-of the shuttle 52, which first of course must be rotated into a position to disgap therein at the lower portion thereof to permit passage of the article therethrough. The wrapping material from the respective reels 63 and 64, is then attached on the article by making a few turns I thereon or by adhesive or other suitable I means, and the lever 12, then moved upto engage the clutch 11, with the 10, whereby the drive shaft The pulley 53, on said which the belt (39, is

wardly driving pulley 7, is caused to rotate. drive shaft around trained, serves to revolve the shuttle 52, at a high rate of speed and the rollers 22 and 23, also receiving their drive from said shaft through the vertical shaft 25, serve to revolve the article X, so that as the wrapper is wound thcrcaround the article of course is moved to revolve and receive a wrapper extending entirely thcrearound. The lever 12, is then thrown downwardly, thus disengaging the clutch 11, and cansing application oi the brake shoe 82, upon the brake drum 81, to stop the machine in a short space of time.

f course articles of different size require the parts of the machine to be adjusted to secure proper alincmcnt and ccntralizing of the article through the eye of the shuttle, and for this pur osc the handle 43, is rotated thus through t e proper gearing connected therewith, actuating the chain 34, which turns the shaft 31, causing the carriage 19, on which the supporting rollers 22 and 23, are mounted, to move upwardly or downwardly, as the case may be, upon the upright guide rods 18. The upper guide rollers 73, bear gravitationally upon the arcntly of each other,

ticle being wrapped, and the pressure with which the same car upon the article is determined b the position of the wei ht 78, which is a jlustable u on the pivoted lever 74, on whic said rollers 73, are mounted. The slight change in the len h of the eriphery of the shuttle over w ich the driving belt 69, tracks when the gap is in an upper position as said shuttle rotates, is compensated for by the adjustable idler pulley 57, mounted on the end of the lever 59, w ich is spring im elled and acts as a tension means for said belt. The lower guide rollers 45, are of course adjustable toward and away from one another for articles of diil'ercnt width merely by actuating the hand wheel 49, which is able gearing t0 the lead screw -16, which actuates the brackets for said rollers on said carriage 19. i

am aware that various details of constructionmay be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. A wrapping machine of the class described comprising a frame, an adjustable carriage mounted therein, power driven su porting rollers for an article mounted in said carriage, means for adjusting said carriagr. a chain and sprocket for operating said means, a plurality of alining rollers carried on said carriage means for adjusting the same across the iace of the supporting roller and mechanism for applying a wrapper upon the article.
